All About Optics
Rifle scopes allow you to specifically align a rifle at different targets by aligning your eye with the target over a range. They accomplish this through zoom using a set of lenses within the scope. The scope’s alignment can be adapted for consideration of numerous natural considerations like wind speed and elevation to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based upon the sight picture you are seeing via the optic as you align the scope’s crosshair or reticle with the target. Most modern-day rifle scopes have about eleven parts which are located within and on the exterior of the optic. These parts include the rifle scope’s body, lenses, adjustment dials or turrets, objective focus rings, and other components. Learn about the eleven parts of scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Selecting the perfect type of rifle optic depends on what type of shooting you plan on doing.
About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These types of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where estimations are low
- Experienced shooters who know their target “hold over” and also “lead” ratios for their firearms
- Shooters who don’t mind the reticle is bigger and requires more visual eyesight space than a SFP reticle
About Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle to the rear of the magnifying lens. This causes the reticle to stay at the very same dimensions in relation to the level of magnification being used. The effect is that the reticle measurements alter based upon the zoom employed to shoot over longer ranges due to the fact that the reticle measurements present various increments which can vary with the magnification. In the FFP illustration with the SFP optic, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick. These types of scopes are handy for:
- Far away types of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots occur within much shorter ranges and distances
- Shooters who select a clearer optic picture with less space used up by the enlarged FFP reticle
Magnification for Optics
The quantity of zoom a scope offers is determined by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Power Lens Scope Info
A single power rifle optic comes with a magnification number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not adjust considering that it is a fixed power optic.
Info on Variable Power Lens Rifle Optics
Variable power rifle scopes use variable power levels. The power modification is handled by making use of the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range of Rifle Optics
Here are some suggested scope powers and the ranges where they could be efficiently used. High power optics will not be as efficient as lower powered glass considering that too much zoom can be a bad thing. The same concept applies to longer ranges where the shooter needs to have increased power to see precisely where to best aim the rifle.
About Rifle Optic Lens Coating
All present day rifle scope and optic lenses are covered. Lens coating can be an important aspect of a shooting system when thinking about high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some scope makers also use “HD” or high-definition lens coverings which use different procedures, components, polarizations, and chemicals to draw out different colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Various optic lenses can also have different finishings applied to them. All lenses normally have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while minimizing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope manufacturer and how much you paid for it.
Some scope makers also make it a point to define if their optic lenses are layered or “multi” covered. Being “better” depends on the manufacturer’s lens treatment innovation and the quality of products used in developing the rifle scope.
Hydrophobic Covering for Rifle Scopes
Water on an optical lens does not support keeping a clear sight picture through an optic whatsoever. Numerous top of the line and high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It treats the exterior surfaces of the Steiner glass lens so the water particles can not bind to it or create surface tension. The result is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Choices for Mounting Rifle Optics on Firearms
Mounting approaches for scopes can be found in a couple of choices. There are the basic scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also normally are made in quick release versions which use manual levers which permit rifle shooters to rapidly install and remove the scopes.
Hex Key Glass Rings
Basic, clamp-on type mounting optic rings use hex head screws to position to the flattop design Picatinny scope mount rails on rifles. These varieties of scope mounts use a pair of detached rings to support the optic, and are made from 7075 T6 billet aluminum or similar materials which are created for long distance accuracy shooting. This form of scope mount is very good for rifle systems which are in need of a long lasting, unfailing mount which will not shift despite how much the scope is moved about or abuse the rifle takes. These are the type of mounts you really want to have for a devoted optics setup on a long distance hunting or interdiction rifle which will rarely need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on screws to prevent the hex screws from wiggling out after they are mounted tightly in place. An example of these rings are the 30mm type made by Vortex Optics. The set generally costs around $200 USD
Optic Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. If they all use a comparable style mount, several scopes can also be swapped on the range. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top style Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while preserving the original sighting settings. These types of mounts are useful and beneficial for rifles which are moved around a lot, to remove the glass from the rifle for protection, or for aiming systems which are employed between numerous rifles. An example of this mount type is the 30mm mount from Vortex Optics. It usually costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Wetness inside your rifle optic can spoil a day of shooting and your costly optic by inducing fogging and creating residue within the scope’s tube. A lot of optics protect against wetness from going into the scope tube with a system of sealing O-rings which are water resistant. Usually, these water-resistant optics can be submerged within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be ample moisture avoidance for basic use rifles for hunting and sporting purposes, unless you anticipate taking your rifle aboard watercrafts and are worried about the optic still working if it goes over the side and you can still find the gun.
Gas Purged Rifle Glass Tubes
Another element of avoiding the buildup of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is already occupied by the gas, the glass is less influenced by temperature changes and pressure distinctions from the external environment which may potentially allow water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
